What does the Bible say about being the surety for others?

Scripturally, Jesus Christ is depicted as the everlasting surety for His people, meaning He has taken responsibility for their sins and is their substitute before God. This concept is grounded in biblical passages that affirm His role in the covenant of grace, where He promises to bear the blame and consequences for His elect. As seen in Isaiah 53, Christ was wounded for our transgressions, and it was through His suffering and sacrifice that we are made righteous before God. This act of ensuring our salvation illustrates how essential it is for believers to trust not in their works but in Christ’s completed work on the cross.
